SHINGLE-MACHINE.

Specification of Letters Patent;

Patented Aug. 12, 1919.

To all whom it may concern:

Br it "nown that I, Go'rrrnm Humnuno, a citizen of the United States,residing at (3 929 Soiith Laflin street, Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Shingle-Machines, of which the following is a specification.

This invention relates to a shingle cutting machine. It relates moreparticularly to an. improvement by which the shingles, as theyiLl'GZL'llll from a sheet of shingle-making material, are kept separatefromeach other and prevented from becoming mixed or trossed. Theinter-mingling. which occurs without the use of this improvement causesdifliculty in sorting and packing the individual shingles in neat,compact, and regularly arranged piles. v

The invention is applied to that class of shingle cutting machine inwhich a flexible sheet of shingle-formin material is slit longitudinallyto form shingles of the proper width and is cut oil at regular intervalsto form the shingles of proper length. Such machines have given troubleon account of the tendency the severed shingles have of falling acrosseach other or the edges of the same overlapping and causing the shinglesto become mixed or out of alinement with each other.

The invention will be understood by reference to the accompanyingdrawings in which:

Figure l is a plan view of the machine;

Fig. 2 is a side View of the same;

Fig. 3 is a side View showing a different position of the cutter; and

Fig. 4 is a perspective view of the cutter, showing the separatingdevice thereon.

In the figures, reference character 1 represents a sheet of flexiblematerial out of which shingles are made. This sheet is fed forward inthe direction of the arrow by the usual means (not shown) along the bed2 and under the slittiugdisks 3 mounted upon roller 4 and over the bedplate knife 5 where the sheet is cut transversely by the cutter 6.

The cutter 6 is mounted upon the revolving roller 7 which is driven byany convenient means such as gear wheel 8. Mounted upon the roller 7 isa sheet of metal 9 exi tending partly around the roller 7 and disposedat such a distance from the axis 10 is maintained between the outsidesurface of said sheet 9 and the bed plate knife 5 to permit the shinglesheet to pass therethrough as the roller 7 revolves. Upon the outside ofthe sheet 9 are a number of cirof rotation of roller 7 that suflicientspace cumferen-tially disposed wires or strips of wires 11, divide thechute 13, down which the shingles slide, into a number of compartments.These plates 12 have their ends which are in proximity to the roller 7cut away as shownat 14 so that the outside of the wires 11 on sheet 9almost touch the same as the roller 7 revolves. 15 is a receptacle intowhich the severedzand sepa-- rated shingles fall.

The operation is as follows: The sheet 1 of shingle-making material ofproper width is 'assed along the bed 2 under the cutting r0 ler 4: whereit is slitted by means' of the slitting disks -3. Theslitted sheet thenpasses over the bed plate knife 5 until the proper length extendsthereover when the knife 6 mounted upon the roller 7 descends and seversthe sheet. As shown in Fig. 2, the slitted sheet 1 just'before beingsevered by knife 6 follows alon the outside of the sheet 9 and is guidedtierebywith the wires 11 slightly separating the slitted ends so thatthey Wlll readily pass into the compartments formed by the plates 12 andbe prevented from intermingling as they slide down the chute 13 into thereceptacle -15. It will be noted that the slitted ends of the sheet 1pass into the spaces between the plates 12 before the sheet is severedby the knife 6 so that it is impossible for the shingles to cross eachother however rapid the cutting. operation may be. Because of the factthat the outside of the wires 11 almost touch the rounded edges 14 ofplates 12, the space between the shingles when they are cut ispractically closed. This makes it certain that the group of shingleswill be maintained entirely separated from-each other and cause theshingles to be piled in the receptacle in as many regular and neat pilesas there are slitted ends of the sheet.

Various changes may be made in the details without departing from thespirit and scope of the invention.

What I claim and desire to secure by Letters Patent is:

i 1. In a shingle cuttin machine, a slitter to divide a sheet of roofingmaterial into a plurality of strips, a severing knife to out said stripstransversely, and means to prevent shingles in transverse rows fromintermingling after being severed.

2. In a shingle cuttin machine, a slitter to divide a sheet of roofingmaterial into a 'plurality of strips, a severing knife to out endsbefore severing the same.

4c. In a device of the character-described,

means for slitting a shingle strip, means for severing the sllts andmeans for positively separatlng the slitted ends before severing.

volving guiding means associated with said knife, and separating meansrevolving with said guiding means.

'7. In a device of the class described, in combination a revolvingknife, a circumferentially disposed sheet of metal havingcircumferential wires on the outside thereof revolving with said knife,vertical plates disposed substantially in the same planes as said wires,said plates being cut away in proximity to said sheet so that said wirespass along said cut away portion.

In testimony whereof I aflix my signature.
